技術分野
本願発明は、紙・合成樹脂紙・木板・金属薄板・食品加工物等のシート状物に凹凸を付与する凹凸付与装置に関するものである。
背景技術
シート状の物に凹凸を付けたものは、装飾性が優れたものとして装飾素材として、また拭き取り効果が向上することから拭き取り紙として使用されてきている。
しかし、シート状の物に凹凸を付けたものは、単に上記のような用途に限られるものではなく、凹凸の突起性を利用して磨き紙として、古紙・廃紙を利用したものは凹凸の吸着性を利用して油分等の吸い取り紙として、また凹凸のクッション性を利用して梱包材としてのパッキング材として利用できるものである。
しかるに、凹凸を付与する工程は専用の製造装置を用いて大規模にかつ工業的に行われており、これでは手近にある素材、たとえば模様紙・合成樹脂紙・アルミ箔、を利用して凹凸を付与して自由に好みにあった装飾紙として手軽に利用することは困難であり、また手近にある古紙・廃紙、たとえば新聞紙・複写済用紙、を利用して手軽に凹凸を付与して吸着紙・磨き紙として安価に日常の用途に供することは困難である。
このような課題に対処するべく、外周に凹凸を設けた円形板を多数重ねてローラーを形成し、該ローラー２個を相互に噛み合わせ、ローラー間にシート状物を通すことによりシート状物に凹凸を付与する装置については、発明者・出願人の一名による日本国特許願（特願平１０−３７６６９８）（以下「該出願」という。）がある。
該出願による凹凸付与装置はシート状物に外観上統一のとれた美的感覚に優れた凹凸を付与しうるが、外周に凹凸を設けた同一板厚の板からなる円形板（以下「凹凸付き円形板」という。）を多数重ねてローラーを形成するため、円形板の厚さの公差や、凹凸製造工程時、たとえば打ち抜き時・レーザー加工時、に発生するかえり・せん断溶け等の加工ひずみの影響を免れることができない。
即ち、噛み合うべき二つのローラー表面を形成する凹凸付き円形板（複数）がローラー軸方向に相互に同一厚さで構成されなければ噛み合わず、凹凸付き円形板（複数）の厚さに相違があると噛み合いがうまくいかず、少し噛み合いがよくない場合でも両ローラーを連動させて回転することすら困難な場合がある。
このため、該出願の凹凸付与装置の組立時には、数枚ごとに厚さが一定値に納まるようにいちいち加工調整しなければならず、このため凹凸付与装置を安価に製造するには支障が生じている。
また、凹凸付与装置によって付与される凹凸には、用途によっては外観上統一のとれた美的感覚の優れた凹凸までは要求されない場合も多い。
また、該出願による凹凸付与装置は凹凸付き円形板のみを多数重ねてローラーを形成しているため、噛み合い不良を防止すべく凸部（２１）を先鋭化、たとえば載頭四角錐化（第９図）、せざるを得ない場合があり、軽量・安価な間隔保持機構を設ければ済む場合でも凹凸付き円形板を設けねばならず、その結果ローラー自身の重量を重くさせる一因となる。
さらに、薄いシート状物の場合その性状によっては凹凸加工されたシート状物がローラーに巻き付く場合があり、これを防止するため複数の針状棒をローラーの噛み合い箇所の近くに設けるが、該出願による凹凸付与装置は凹凸付き円形板のみを多数重ねて凹凸を密集させているため針状棒の先端をローラー表面近くに寄せるには限度があった。
発明の開示
本願発明は、上記のような事情のもとで考えだされたものであって、凹凸付き円形板の板厚そのものの公差や凹凸加工時のひずみによる厚みの変動を簡易に修正し得る手段を提供すること、また、凹凸の加工具合を必要に応じて自由に調整しうる凹凸付与装置を提供すること、さらに、一層軽量な凹凸付与装置を提供すすることを目的とするものである。
本願発明の目的は、凹凸付き円形板にまたは凹凸付き円形板の間に間隔保持機構をもたせたことを特徴とする装置を提供することによって達成される。
間隔保持機構としては一般には輪状の間隔保持板（以下「スペーサ」という。）が使用されるが、一体成形が可能な素材、たとえば合成樹脂材、の場合には凹凸付き円形板と間隔保持板とを一体として構成することもできる。
以下においては、間隔保持機構としてスペーサを利用した場合について述べる。
また本願発明による装置は、請求の範囲第１項に記載した発明において、回転自在に固定した一のローラーに、対向ローラーを自重または押し付け機構によって押し付けて、一のローラーの凹凸と対向ローラーの凸凹とが相互に噛み合うようにし、一のローラーを回転させることにより対向ローラーを連動回転させることを可能にしたことによって一層効果的に達成される。
発明を実施するための最良の形態
以下、本願の好ましい実施の形態を、添付図によって具体的に説明する。
第４図は凹凸付与装置の使用状況を示す概略図である。
一のローラー（１）と対向ローラー（２）の間にシート状物（６）を通し、ローラー表面の凹凸模様（５）で、シート状物に凹凸を付与させるものである。
第１図ないし第３図は、本願発明の請求の範囲第１項に相当する発明の実施の形態を示す。
第２図は凹凸付き円形板（２０）、第３図はスペーサ（２８）を示し、第１図はこれらを組み立てたローラー（１、２）を示す。
凹凸付き円形板の厚さは、要求される凹凸の大きさや凹凸加工されるシート状物の厚さ・性状によって決定されるが、一般には１ｍｍないし３ｍｍ程度が使用される。
凹凸付き円形板の内径側には突起（２６）を設け、該突起はローラー軸（２３）に設けたキー溝（２７）に嵌合するようにして、凹凸付き円形板の凹凸の位置がずれないようにしてある。
なお突起は単数でもよくまた複数設けてもよい。
また、突起の位置を適切に設計することにより、一種類の凹凸付き円形板を表裏交互に嵌合することにより、円形板の凹凸のピッチを適宜ずらすこともできる。凹凸付き円形板（２０）には、鋼・アルミ・ステンレス鋼・チタン・銅等の金属材料の他、硬質の樹脂・ゴム等の非金属材料も使用される。
第７図に、一のローラー（１）の凸部の側部と対向ローラー（２）の凸部の側部とが隣接する関係にある場合を示すが、この場合にはこの両ローラーの凸部間でシート状物にせん断効果（鋏の効果）を働かせることができることから、このせん断効果と凹凸付き円形板の凹凸形状を考慮して、スペーサ（２８）の厚さを決定することもできる。
通常使用されるスペーサの厚さは０．５ｍｍないし２ｍｍである。
スペーサの外径は、シート状物（６）の厚さ・性状等を考慮して、各構成部品の加工精度が良い場合で上述のせん断効果を効果的にするときは凹凸付き円形板の凹部を形成する径より大きな径とすることもできるが、一般には凹凸付き円形板の凹部を形成する径と同等かあるいはそれより小さな径が採用される。
内径はローラー軸の径を基準として公差を考慮して決定される。
スペーサの材質には凹凸付き円形板（２０）と同材質のものも採用できるが、硬質の非金属材料を使用すると、軽量・安価に製作することができる。
ローラー（１、２）は、第１図に示すように、ローラー軸（２３）の始端で嵌合した止め輪（２５）、当て板（２４）を介して凹凸付き円形板（２０）、スペーサ（２８）、凹凸付き円形板、スペーサの順に嵌合し、終端も始端と同様に当て板、止め板で把持・固定することによって組立・構成される。
なお、止め輪の代わりにボルト・ナット機構を採用してもよい。
ローラーの凹凸部分の長さは、凹凸加工されるシート状物（６）の加工幅・装置の価格等を考慮して決定され、家庭用の小さな装置では１５０ｍｍ程度、企業用の装置では３００ｍｍ程度である。
また、ローラー軸径は、ローラーの凹凸部分の長さや凹凸加工されるシート状物（６）の性状を考慮して決定されるが、家庭用の小さな装置では２０ｍｍ程度、企業用の装置では３６ｍｍ程度である。
もちろんローラーの凹凸部分の長さやローラー軸径は、必要に応じ、より小さなあるいはより大きな寸法のものも製作できる。
第７図は、凹凸付き円形板の凸部（２１）の頂部から凹部をみた図であって、理解しやすいように凸部は太い実線で、凹部は破線で示し、凹凸付き円形板を半ピッチずらして描いたものである。
なお、ローラー軸方向に切断した断面をＡ矢視図として、両ローラーの噛み合い状況も示した。
その場合に期待できる効果については上述した通りである。
凹凸付き円形板の凸部の形状は、第８図に示すように、円形板の外周に向かって板厚方向にテーパをとることもでき、そのテーパも板の両面で異なるテーパとすることもできる。
このテーパをとることによって、両ローラーの噛み合いを容易にすることができる。
凹凸付き円形板の凸部の形状は、第９図に示すような載頭四角錐形状を基本形状として、凸部先端の円周方向の厚さを薄くすると第１０図が得られ、凸部先端の板厚方向の厚さを薄くすると第１１図・第８図に示す形状が得られる。
もちろん板厚そのものを利用して凸部先端の円周方向の厚さを薄くすることもでき、その場合には第７図に示す形状のものも得られる。
載頭四角錐の凸形状は、四角錐の凸形状に比べて、底部矩形部の面積が同一であって同一径の円形板であれば、シート状物により多くの表面積を形成することができ、より大きな吸着効果を凹凸加工物に与えることができるという利点を有している。
また、凸部分と凹部分の円周方向長さを異なるものにして、ローラー（１）とローラー（２）を噛み合うようにしてもよい。
なお、第１０図中のＢ断面および第１１図中のＣ断面は、凹凸付き円形板の板厚中心における断面を、凹凸の形状を理解しやすくするために、円形板の円部分を直線状にして描いたものである。
第５図および第６図は、本願発明の請求の範囲第２項に相当する発明の実施の形態を示す。
第５図は装置を正面からみた場合の断面図、第６図は側面図である。
台板（１４）には、一対の側柱（１１）・上板（１５）からなる側壁ブロックが左右一対ねじ等により固着される。側壁ブロック内には、下部ピース（１６）が設けられ、さらにその上部に下部軸受台（１２）・上部軸受台（１３）が側柱間にスライド自在に嵌合されている。
左右一対の下部軸受台にはローラー（１）が軸受を介して取り付けられ、また左右一対の上部軸受台にはローラー（２）が軸受を介して取り付けられ、上部軸受台は上板（１５）に螺合されたねじ（１７）と隙間調整つまみ（１８）からなる押し付け機構によって下方に押し付けられ、シート状物の厚さや性状に応じてローラー間の隙間を自在に調整できるようになっている。
手動ハンドル（１９）を回すと、ローラー（１）およびローラー（２）が回転しシート状物に凹凸が付与される。
なお、上部軸受台の上端とねじの下端との間にコイルばねを介在させることもできる。
シート状物が薄い場合には、ローラー（２）の自重だけで凹凸を付与することもできる。
産業上の利用の可能性
本願発明は、以上説明したような形態で実施され、スペーサを設けることにより以下に記載されるような顕著な産業上の利用の可能性を奏する。
スペーサを設けることにより、円形板の厚さの公差や、凹凸製造工程時、たとえば打ち抜き時・レーザー加工時、に発生するかえり・せん断溶け等の加工ひずみの影響を簡易に処理することが可能になる。
たとえば打ち抜き加工時に発生するかえりを除去するためのバレル加工が不要となる。
スペーサの形状としては、凹凸付き円形板内径部に設けた突起のごとく空回りを阻止する機構を設ける必要がなく、輪状の簡単な構造のものを採用しうることから製作が容易であり安価のものを採用することができる。
また、このような形状のスペーサで厚さの異なる数種のスペーサを用意すれば、複数枚からなる凹凸付き円形板のブロックを同一厚さにすることが極めて容易になり、このようにブロック分けした複数枚からなる凹凸付き円形板のブロックをさらに積み重ねることにより、凹凸の位置精度の良い長尺なローラーを簡易に組み立てることが可能になる。
さらに、スペーサの外径を凹凸付き円形板の凹部底を構成する円の直径より小さくすることによって凹凸部分の加工ひずみ、たとえば打ち抜きのかえり・レーザー加工のせん断溶け、の影響を受けなくすることができる。
以上の諸効果から複雑な形状の凹凸付き円形板そのものを調整加工する必要がなくなり、装置を安価に提供できることになる。
従来の凹凸付与装置は円形板のみを多数重ねてローラーを形成しているため、噛み合い不良を防止すべく凸部を先鋭化、たとえば載頭四角錐化、せざるを得ない場合があり、軽量・安価な間隔保持機構を設ければ済む場合でも凹凸付き円形板を設けねばならず、その結果ローラー自身の重量を重くさせかつ装置を高価にさせる一因となっていたが、スペーサを設けることにより上記のごとき必要性のない加工を省略できるとともに、それに代わって軽量のスペーサが採用できることから、装置全体の軽量化と安価化を図ることが可能となった。
一のローラー（１）の凸部の側部と対向ローラー（２）の凸部の側部とが隣接する関係にある場合はこの両ローラーの凸部間でシート状物にせん断効果（鋏の効果）を働かせることができることから、スペーサの厚さを小さくすることによりせん断効果を強く働かせることができ、この部分においてシート状物に開孔を形成することも可能になる。
これにより紙のシート状物にはより大きな吸着性能を持たせることができ、油分等の吸着紙としての用途をさらに広げることが可能となる。
薄いシート状物が凹凸加工後ローラーに巻き付く場合があるが、これを防止するための複数の針状棒をスペーサ部分に設けることにより、ローラーの回転に支障を生じることなくシート状物の巻き付きを確実に防止することができる。
なお、段ボール素材のような空芯を有する素材の場合には、両ローラーの凹凸を噛み合わせる必要は必ずしもなく、単に凸部で開孔を設けるだけで吸着性を高めることができる。

Background Art A sheet-like material with irregularities has been used as a decorative material because of its excellent decorativeness, and as a wiping paper because of its improved wiping effect.
However, a sheet-like object with unevenness is not limited to the above-mentioned use. As a polishing paper using uneven protrusions, a thing using waste paper / waste paper is uneven. It can be used as a blotting paper for oil and the like by using the adsorptive property, and as a packing material as a packing material by using the cushioning property of the unevenness.
However, the process of imparting irregularities is carried out on a large scale and industrially using a dedicated manufacturing device, which uses irregular materials such as patterned paper, synthetic resin paper, and aluminum foil. It is difficult to easily use it as a decorative paper that suits your taste, and you can easily add unevenness using old and used paper such as newspaper and copied paper. It is difficult to use it for daily use at a low cost as an adsorbent paper or polishing paper.
In order to cope with such a problem, a large number of circular plates having irregularities on the outer periphery are stacked to form a roller, the two rollers are meshed with each other, and the sheet-like material is passed between the rollers to form a sheet-like material. Regarding an apparatus for imparting irregularities, there is a Japanese patent application (Japanese Patent Application No. 10-376698) (hereinafter referred to as “the application”) by one inventor / applicant.
The concavo-convex imparting device according to the application can impart concavo-convex with an aesthetic sense that is uniform in appearance to a sheet-like material. Because the roller is formed by stacking a large number of plates, the influence of the thickness tolerance of the circular plate and the influence of processing strain such as burr and shear melting that occurs during the uneven manufacturing process, for example, punching and laser processing. Can not escape.
That is, if the concave and convex circular plates forming the two roller surfaces to be engaged with each other are not configured to have the same thickness in the roller axis direction, they do not engage with each other, and the thickness of the concave and convex circular plates is different. In some cases, even if the meshing is not good and the meshing is not good, it is even difficult to rotate both rollers together.
For this reason, when assembling the unevenness imparting device of the application, it is necessary to adjust the processing so that the thickness is kept at a constant value every few sheets. ing.
In addition, the unevenness imparted by the unevenness imparting device is often not required to have unevenness with an aesthetic feeling that is uniform in appearance depending on the application.
In addition, since the unevenness imparting device according to the application forms a roller by stacking only a large number of circular plates with unevenness, the convex portion (21) is sharpened, for example, a truncated quadrangular pyramid (No. 9) is formed in order to prevent poor meshing. (Figure), there is a case where it is necessary to provide a light and inexpensive spacing holding mechanism, it is necessary to provide a circular plate with irregularities, which contributes to increase the weight of the roller itself.
Furthermore, in the case of a thin sheet material, depending on the property, the uneven sheet material may be wound around the roller, and in order to prevent this, a plurality of needle-like bars are provided near the engagement position of the roller. The unevenness imparting device according to the application has a limit in bringing the tip of the needle bar closer to the roller surface because only a large number of circular plates with unevenness are stacked to close the unevenness.
DISCLOSURE OF THE INVENTION The present invention has been conceived under the circumstances as described above, and it is possible to easily correct variations in thickness due to the tolerance of the thickness of the circular plate with unevenness and distortion during uneven processing. It is intended to provide a means for obtaining, to provide an unevenness imparting device that can freely adjust the unevenness processing condition as needed, and to provide a lighter unevenness imparting device. is there.
The object of the present invention is achieved by providing an apparatus characterized in that an interval holding mechanism is provided on or between the uneven circular plates.
In general, a ring-shaped interval holding plate (hereinafter referred to as a “spacer”) is used as the interval holding mechanism. However, in the case of a material that can be integrally molded, for example, a synthetic resin material, an uneven circular plate and an interval holding plate are used. Can be configured as a unit.
Below, the case where a spacer is utilized as a space | interval holding | maintenance mechanism is described.
The apparatus according to the present invention is the device according to
BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings.
FIG. 4 is a schematic view showing the usage of the unevenness imparting device.
The sheet-like material (6) is passed between one roller (1) and the opposing roller (2), and the unevenness (5) on the roller surface is imparted to the sheet-like material.
1 to 3 show an embodiment of the invention corresponding to claim 1 of the present invention.
Fig. 2 shows a circular plate with concaves and convexes (20), Fig. 3 shows a spacer (28), and Fig. 1 shows rollers (1, 2) assembled with them.
The thickness of the circular plate with unevenness is determined by the required size of the unevenness and the thickness and properties of the sheet-like material to be processed, but generally about 1 mm to 3 mm is used.
A protrusion (26) is provided on the inner diameter side of the concave and convex circular plate, and the protrusion is engaged with a key groove (27) provided on the roller shaft (23) so that the concave and convex positions of the concave and convex circular plate are displaced. There is no way.
A single protrusion or a plurality of protrusions may be provided.
In addition, by appropriately designing the positions of the protrusions, the pitch of the unevenness of the circular plate can be appropriately shifted by fitting one type of uneven circular plate alternately on the front and back. In addition to metal materials such as steel, aluminum, stainless steel, titanium, and copper, non-metallic materials such as hard resin and rubber are also used for the concave and convex circular plate (20).
FIG. 7 shows a case where the side of the convex portion of one roller (1) and the side of the convex portion of the opposing roller (2) are adjacent to each other. Since the shear effect (the effect of wrinkles) can be exerted on the sheet-like material between the portions, the thickness of the spacer (28) can be determined in consideration of the shear effect and the uneven shape of the circular plate with unevenness. .
A commonly used spacer has a thickness of 0.5 mm to 2 mm.
The outer diameter of the spacer is a concave portion of a concave and convex circular plate in consideration of the thickness and properties of the sheet-like material (6) when the processing accuracy of each component is good and the above shear effect is effective. However, generally, a diameter equal to or smaller than the diameter for forming the concave portion of the concave and convex circular plate is employed.
The inner diameter is determined in consideration of tolerances based on the diameter of the roller shaft.
The spacer can be made of the same material as the concave and convex circular plate (20). However, if a hard non-metallic material is used, the spacer can be manufactured at a light weight and at a low cost.
As shown in FIG. 1, the rollers (1, 2) include a retaining ring (25) fitted at the starting end of the roller shaft (23), a circular plate with concaves and convexes (20) via a backing plate (24), a spacer (28), an uneven circular plate and a spacer are fitted in this order, and the end is assembled and configured by holding and fixing with a backing plate and a stop plate in the same manner as the starting end.
A bolt / nut mechanism may be employed instead of the retaining ring.
The length of the rugged portion of the roller is determined in consideration of the processing width of the sheet-like material (6) to be rugged processed, the price of the device, etc., about 150 mm for a small household device and about 300 mm for a corporate device. It is.
The roller shaft diameter is determined in consideration of the length of the uneven portion of the roller and the properties of the sheet-like material (6) to be processed, but it is about 20 mm for a small household device and 36 mm for a company device. Degree.
Of course, the length of the uneven portion of the roller and the roller shaft diameter can be made smaller or larger as required.
FIG. 7 is a view of the concave portion from the top of the convex portion (21) of the concave-convex circular plate. For easy understanding, the convex portion is indicated by a thick solid line, the concave portion is indicated by a broken line, and the concave-convex circular plate is half-finished. It is drawn with a pitch shift.
In addition, the cross section cut | disconnected in the roller axial direction was made into arrow A view, and the meshing condition of both rollers was also shown.
The effects that can be expected in this case are as described above.
As shown in FIG. 8, the shape of the convex portion of the circular plate with unevenness can be tapered in the thickness direction toward the outer periphery of the circular plate, and the taper can also be different on both sides of the plate. it can.
By taking this taper, the engagement of both rollers can be facilitated.
The shape of the convex portion of the circular plate with concaves and convexes is shown in Fig. 10 when the circumferential thickness of the tip of the convex portion is made thin with the mounting quadrangular pyramid shape as shown in Fig. 9 as the basic shape. When the thickness of the tip in the plate thickness direction is reduced, the shapes shown in FIGS. 11 and 8 are obtained.
Of course, the thickness in the circumferential direction at the tip of the convex portion can be reduced by using the plate thickness itself, and in this case, the shape shown in FIG. 7 can be obtained.
The convex shape of the headed quadrangular pyramid can form a larger surface area on the sheet-like material if the bottom rectangular part has the same area and the same diameter, as compared to the convex shape of the quadrangular pyramid. And, it has the advantage that a larger adsorption effect can be given to the concavo-convex workpiece.
Further, the circumferential lengths of the convex portion and the concave portion may be different to engage the roller (1) and the roller (2).
The cross section B in FIG. 10 and the cross section C in FIG. 11 show the cross section at the center of the thickness of the circular plate with concaves and convexes so that the circular part of the circular plate is straight to make the shape of the concaves and convexes easy to understand. It is drawn by.
5 and 6 show an embodiment of the invention corresponding to claim 2 of the present invention.
FIG. 5 is a sectional view of the apparatus as viewed from the front, and FIG. 6 is a side view.
A side wall block composed of a pair of side columns (11) and an upper plate (15) is fixed to the base plate (14) with a pair of left and right screws or the like. A lower piece (16) is provided in the side wall block, and further, a lower bearing base (12) and an upper bearing base (13) are slidably fitted between the side columns.
A roller (1) is attached to the pair of left and right lower bearing bases via bearings, and a roller (2) is attached to the pair of left and right upper bearing stands via bearings, and the upper bearing base is an upper plate (15). Is pressed downward by a pressing mechanism comprising a screw (17) and a gap adjustment knob (18) screwed together, and the gap between the rollers can be freely adjusted according to the thickness and properties of the sheet-like material. .
When the manual handle (19) is turned, the roller (1) and the roller (2) are rotated to give unevenness to the sheet-like material.
A coil spring can be interposed between the upper end of the upper bearing base and the lower end of the screw.
When the sheet is thin, irregularities can be imparted only by the weight of the roller (2).
Industrial Applicability The present invention is implemented in the form as described above, and by providing a spacer, there is a remarkable industrial applicability as described below.
By providing a spacer, it is possible to easily handle the effects of processing strain such as burr and shear melting that occur during the manufacturing process of irregularities, for example, punching and laser processing, etc. Become.
For example, barrel processing for removing burr generated at the time of punching is not necessary.
As for the shape of the spacer, it is not necessary to provide a mechanism for preventing idle rotation like the projection provided on the inner diameter part of the concave and convex circular plate, and since a simple ring-shaped structure can be adopted, it is easy to manufacture and inexpensive. Can be adopted.
In addition, if several types of spacers with different thicknesses are prepared in this way, it is very easy to make a plurality of uneven circular plate blocks with the same thickness. It is possible to easily assemble a long roller having a high position accuracy of the unevenness by further stacking the blocks of the uneven circular plates made of a plurality of the unevenness.
Furthermore, by making the outer diameter of the spacer smaller than the diameter of the circle constituting the concave bottom of the concave and convex circular plate, it is possible to eliminate the influence of processing distortion of the concave and convex portions, for example, punching burr and laser processing shear melting. it can.
From the above effects, it becomes unnecessary to adjust the complicatedly shaped circular plate with unevenness, and the apparatus can be provided at low cost.
Since the conventional unevenness imparting device forms a roller by stacking only a large number of circular plates, it may be necessary to sharpen the convex part, for example, to make it a quadrangular pyramid, in order to prevent poor meshing, and light weight・ Even if it is only necessary to provide an inexpensive spacing mechanism, it is necessary to provide a circular plate with irregularities, which results in increasing the weight of the roller itself and making the device expensive. Thus, unnecessary processing as described above can be omitted, and a lightweight spacer can be used instead. Therefore, it has become possible to reduce the weight and cost of the entire apparatus.
When the side of the convex part of one roller (1) and the side of the convex part of the opposing roller (2) are adjacent to each other, a shearing effect is exerted on the sheet-like material between the convex parts of both rollers ( Therefore, the shearing effect can be exerted strongly by reducing the thickness of the spacer, and it is also possible to form a hole in the sheet-like material at this portion.
As a result, the paper sheet can have a larger adsorption performance, and the use of the oil as an adsorption paper can be further expanded.
A thin sheet-like material may be wound around the roller after uneven processing, but by providing a plurality of needle-like bars in the spacer part to prevent this, the sheet-like material can be wound without causing any trouble in the rotation of the roller. Can be reliably prevented.
In the case of a material having an air core such as a corrugated cardboard material, it is not always necessary to mesh the unevenness of both rollers, and the adsorptivity can be improved simply by providing an opening at the convex portion.
